Impedance-Based VSC Unit Commitment with STATCOM Support under High IBG Penetration

Aoun Abbas, Charalambos Konstantinou, Zhongda Chu

A mixed-integer second-order cone program for unit commitment embeds voltage stability boundaries and synthetic inertia to maintain security and lower costs with high inverter-based generation, with STATCOM adding dispatch gains.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Simulation results show that the proposed framework enhances voltage security, maintains frequency-nadir compliance, and reduces operating cost, while STATCOM integration further improves dispatch feasibility under high IBG.

C2weakest assumption

That the second-order cone relaxation of the voltage stability boundary remains tight and accurate for the modified IEEE 30-bus system under the chosen high-IBG scenarios and that the 30 MVAr STATCOM placement is representative of practical weak-grid locations.

C3one line summary

An optimization framework co-optimizes unit commitment with synthetic inertia dispatch and STATCOM reactive support to maintain both voltage and frequency stability under high inverter-based generation.
